Our client is a small family owned financial services organization operating in a fast‑paced, high‑touch enterprise environment. They are looking for a dedicated technology professional to drive continuous improvement, stability, and reliability across their corporate office environments.

In this role as a Senior Systems Administrator, you will serve as a hands‑on technical leader and the day‑to‑day owner of IT operations. Working closely with engineering management, you will provide deep technical expertise across a robust Windows and Microsoft cloud infrastructure. Crucially, this role requires a true "no task is too small" mentality; you will drive high‑level infrastructure engineering initiatives while remaining happy and willing to roll up your sleeves to resolve foundational desktop and end‑user support tickets as needed.

• Extensive experience with Windows Server administration (Active Directory, DNS, DHCP, Group Policy, Hyper‑V).

• Deep proficiency in Microsoft Cloud environments, specifically Azure (Entra ID, Virtual Machines, Storage, Networking) and M365.

• Hands‑on experience managing multi‑domain forests, multi‑site setups, and hybrid AD environments.

• Proficiency in Linux administration (specifically Debian and Fedora).

• Strong automation and scripting skills, particularly with PowerShell.

• Working knowledge of endpoint management solutions, enterprise WiFi (e.g., Aruba), and network/security fundamentals.

• Proven willingness to handle everyday tier‑1 and tier‑2 desktop support alongside senior engineering tasks.

• Previous experience operating in financial services or a similarly demanding enterprise setting.

Responsibilities

• Own the day‑to‑day administration of both on‑premise and cloud infrastructure across Windows and Linux environments.

• Troubleshoot complex systems issues and perform root‑cause analysis to prevent recurring problems.

• Jump in to assist with foundational IT‑support tasks, eagerly handling everyday end‑user requests and desktop troubleshooting when required.

• Provide high‑touch, executive‑level technical support while managing ticket handling and escalation procedures.

• Create, standardise, and maintain clear IT documentation, SOPs, and runbooks.

• Train, mentor, and provide ongoing feedback to build the technical capabilities of junior team members.

• Manage backup, disaster recovery, and business continuity planning initiatives while participating in an on‑call rotation.

This on‑site position offers a highly competitive base salary ranging from $175,000 to $225,000, commensurate with experience. You will also receive an excellent benefits package that includes an annual discretionary bonus, fully paid health insurance, and generous PTO.
